David Harnick is a board-certified cardiologist and electrophysiologist who is affiliated with The Mount Sinai Medical Center and North Shore LIJ, Lenox Hill Hospital. He is an assistant clinical professor at the Mount Sinai Medical Center, and Director of Outpatient electrophysiology services at The Lenox Hill Hospital.
David Harnick completed his undergraduate training at Rugters University where he graduated summa cum laude as a Henry Rutgers Honors Student.
He completed medical school training at The Mount Sinai School of Medicine in NYC. During his second year of medical school, he was awarded a research scholarship as a Howard Hughes investigator and successfully cloned the first calcium channel in human T-cells. This work has subsequently led to understanding of cellular mechanisms of cell activation and cell cycling.
After graduating from Mount Sinai, he completed his internal medicine residency at Columbia Presbyterian Medical Center.
Subsequently, he returned to Mount Sinai where he performed his training in General Cardiology and Electrophysiology. He joined Dr. Rastegar in practice in 2004.He has been named to the New York Times Super Doctors of New York since 2013 and has been featured yearly in Castle Connelly best physicians.
He continues to lecture to his peers on atrial fibrillation and anticoagulant management and is involved in clinical trials of the above as well as cardiac devices. Dr. Harnick specializes in general cardiology and cardiac electrophysiology. He deals extensively with the diagnosis and management of cardiac arrhythmias and is actively involved in performing cardiac ablations for supraventricular and ventricular arrhythmias as well as atrial fibrillation. He implants pacemakers, defibrillators and cardiac resynchronization devices in patients suffering from congestive heart failure. He has an interest in dealing with patients with dizziness and syncope, and works closely with neurologists to establish diagnosis and treatment plans of patients who suffer from such problems. We have a remote management program at our facility to follow pacemakers and defibrillators from the convenience of your own home.
